Your plants seem pretty small to be giving them nutes unless your soil has no castings in it. If you are giving it nutes I would give them a small dose every 6-10 days. I would also get the PH calibrator solution.

 

[Hammerhead]

I will not be giving any until The problem is corrected. I got some Revive will try that when it arives

Nice! Good luck with those. I wish I had some Bubble Gum. In my soil grow, I don't start them on nutes until 2-3 weeks but I do use a little B1.

Careful with all that light, looks like may have you burnt the lower leaves a little when those leaves were new. They will continue to deteriorate and die, nothing you can do now to save them. Make sure the new growth is green and normal.

I agree, they need some calmag. If you start seeing little brown spots then you are definitely lacking calcium.

I had a good tip only water your plants when the top 3 inches of soil is dry if you water too often not letting the soil dry out your roots will become root bound more quickly mainly at the bottom of your pot. letting your soil dry out will allow the roots to grow throughout the whole pot not just the bottom.If you are using soil(bio bizz ) or similar there is no need to feed plants that small there should be enough feed in the soil. I have also used bottled water and filtered water ph is always diffferent sometimes way off the scale , just make sure your ph is not fluctuating too much ........... good luck dude

I moved 4 plants back to the veg closet with 4 t5 lights. I will apply the revive there and see whats going on after that. my soil is super soil. with perlite added. I have foxfarm on the way just in case . but if they get to big I wont be able to move them. The plants you saw where samll but I have 9 others that are 3 times there size. Im betting I over watered and gave to much ferts.

 

[mdanzig]

Its all in the soil my man. Your soil mixture is key.

 

[Hammerhead]

just a bag of supersoil from HD and a few waterings of ferts. I will be using foxfarm soil from now on. I think I will be ok the rest of the plants look like there recovering from my newbie mistake even though I have grown before in a differant room. I had no problems with that grow but I had very good soil then.
